Summary of the invention
In home-use freezing-cooling storeroom, in the past, typically it is configured with refrigerating chamber in lowermost,
But in recent years, it is provided that at stage casing configuration refrigerating chamber, lowermost is cold as the centre of vegetable compartment
Freeze the freezing-cooling storeroom of storehouse type.In this case, also there is the formations by cooler and periphery thereof
Part (the cold air flow mechanism etc. being made up of pressure fan, cool-air feed pipeline, muffler unit)
Being disposed in the rear side of refrigerating chamber, the front face side in pressure fan arranges the preservation housing of refrigerating chamber
Freezing-cooling storeroom.
Additionally, in the freezer in recent years requiring energy saving, in order to improve energy saving, also
Pay attention to the rear side of refrigerating chamber, i.e. the back side, cooler room is heat insulation.In order to improve such cooling
The heat-proof quality of the rear side of device room, needs to thicken the heat insulation material being filled between outer container and interior case
Thickness, or in heat insulation material, fill the component that the heat transfer coefficient such as vacuum insulation material is low.
In the freezer of patent documentation 1, because the upstream side in pressure fan is provided with for guaranteeing
Suck the recess of air quantity, so air-supply function obtains the air quantity of regulation., because in air-supply
The rear of machine, interior case be provided with cross section arc-shaped big recess (thus, interior case and outer container it
Between become protuberance), so the lower thickness of the heat insulation material in the maximum place of diarrhea of heat type leakage quantity, this
Outward, owing to the thickness of landfill vacuum insulation material in heat insulation material is also restricted, all cannot fill
Divide ground to guarantee heat-proof quality, accordingly, there exist cooling performance low, it is impossible to obtain energy saving such
Problem points.
The present invention is in order to solve above-mentioned problem and to propose, and its object is to, it is provided that a kind of
Cooling performance is excellent and can improve the freezing-cooling storeroom of energy saving.
The freezing-cooling storeroom of the present invention has freezer main body, the front openings of this freezer main body,
